I plan on using a Yugo RPK parts kit and a Coldsteel Solutions receiver blank to build my .308. I will shorten and lighten the barrel before re-chambering it.
I figure on moving the front trunion 1/4 to 5/16 inch forward, and installing the crossbrace about the same amount rearward. I figure this will provide enough room for a .308 Galil magazine.
Time will tell if I am right.
BTW, now I know what happened to the parts missing from the .308 barreled Saiga receivere I purchased.
